that get() could return null
hmmm
any ideas on how to fix that?
after init()
how many nodes in list3
println after init()
4
what is size
should be 4
I see
list3.add("C") will throw
because last node was null
and when you get it... and attempt to set next
the data was null, not the node itself I think
ahh ok
it must be the size then
get(this.size - 1) is returning null
```
ListNode last = get(this.size - 1);
if (last != null) {
last.next = newNode;
++this.size;
return true;
}
return false;
```
thanks
this would only happen adding first node to list I would think
data structures?
or Java class?
Data Structures
I actually have a Java developer certificate but it was a long time ago so I have to relearn everything
Got it same time as I graduated high school
when I took that class we used C
1999 😉
Java was its own class back then - the OOP class
I had to take a 3 part Java series to get into this class
It was part of my certificate
nice
it's a good line of work
I need help factoring a math problem @here
-x^2 + 5x + 14
(-x - 2)(x - 7)
I have meeting in 3 mins
but that is close
Have you been taught any particular methods for factoring?
